Optoma BX-CTA27 Extreme-Long-Throw Motorized Zoom Lens for Select Optoma Projectors

The Optoma BX-CTA27 is an extreme long-throw motorized zoom lens created for projection layouts that require substantial distance between the projector and screen. Optoma identifies it as its longest throw lens, with a 7.2–10.8:1 throw ratio and support for image sizes from 50 inches to 1000 inches. It is designed for the Optoma ZU2200, ZU1900, and ZU1700 DuraCore laser projectors.

Ideal Use Cases

The BX-CTA27 is intended for distance installations and large-venue entertainment where a projector must be positioned far from the screen. Its extreme long-throw range makes it relevant when the room layout, projection position, or installation design calls for more separation than a conventional lens provides.

The supported 50- to 1000-inch image-size range accommodates installations with widely different screen requirements. Smaller configurations can begin at 50 inches, while large-format environments can use images measuring as much as 1000 inches when paired with a compatible projector and an installation that meets the stated throw requirements.

Why Choose This Model

The defining specification of the BX-CTA27 is its 7.2–10.8:1 throw ratio. This range is specifically suited to situations where the projector cannot be placed near the screen. The motorized zoom design provides an adjustable optical range within that stated throw ratio, helping installers configure the projected image for the available distance.

Optoma describes the BX-CTA27 as its longest throw lens. That distinction makes this model a focused choice for projects in which extreme projection distance is a central requirement rather than an optional capability. Its intended role is clearly defined: extending the practical placement distance for compatible Optoma large-venue laser projectors.

Installation and Integration

Compatibility should be confirmed before installation. The supplied manufacturer data specifically identifies the Optoma ZU2200, ZU1900, and ZU1700 DuraCore laser projectors as supported models. No compatibility with other projector models is stated in the available information.

Planning should be based on the 7.2–10.8:1 throw ratio and the required image size. Because the lens covers images from 50 inches through 1000 inches, the selected screen size and projector-to-screen distance should be evaluated together. The motorized zoom range can then be used within the supported optical parameters to establish the intended image framing.

The product listing identifies the BX-CTA27 as a motorized ultra long-throw lens for UB Series WUXGA applications, while the supplied Optoma description specifically names the ZU2200, ZU1900, and ZU1700. For equipment selection and integration, the explicitly named projector models provide the available compatibility reference.

Performance Highlights

• Extreme long-throw optical design for distance installations.
• 7.2–10.8:1 throw ratio.
• Motorized zoom lens operation.
• Supported image-size range from 50 inches to 1000 inches.
• Designed for large-venue entertainment applications.
• Specified for Optoma ZU2200, ZU1900, and ZU1700 DuraCore laser projectors.

These specifications define a lens optimized around projection distance and image-scale versatility. The broad stated image-size range supports both comparatively compact images and very large presentation surfaces, while the extreme throw ratio addresses layouts that place projection equipment well behind the viewing area.

What Makes It Different

The BX-CTA27 stands apart through the combination of Optoma’s longest stated throw capability, a motorized zoom mechanism, and support for images up to 1000 inches. It is not presented as a general-purpose short- or standard-throw accessory. Its purpose is to solve the specific installation challenge of producing an appropriately sized image from an extra-long projector-to-screen distance.

Its dedicated compatibility with three Optoma DuraCore laser projector models also gives it a clearly defined system role. Rather than introducing unrelated features, the BX-CTA27 concentrates on the optical requirements of compatible large-venue projection systems.

Final Assessment

The Optoma BX-CTA27 is a specialized lens for installations where projection distance is the deciding factor. Its 7.2–10.8:1 throw ratio, motorized zoom design, and 50- to 1000-inch image range directly address long-distance and large-format projection requirements. For systems built around an Optoma ZU2200, ZU1900, or ZU1700 DuraCore laser projector, it provides the manufacturer’s extreme long-throw lens option for demanding venue layouts.
